Marker Track Transport

Sensor-primary autonomy has hit a regulatory wall: state DOTs and insurers cannot certify a sensor stack the way they can certify a road segment. This article introduces marker track transport: a primitive in which authority-credentialed marker sequences are the primary routing reference, and per-segment governance-credentialed authorization replaces per-vehicle sensor-stack certification.

Marker-track transport inverts the autonomous-vehicle certification model. The road segment is approved by its regulatory authority through credentialing the markers installed in it. The vehicle is approved to operate on credentialed segments by demonstrating it correctly reads, evaluates, and follows credentialed marker sequences.

Each marker-track segment carries a governance-credentialed attestation by the segment's regulatory authority. The attestation specifies what operating modes are authorized on the segment, what classes of vehicles are admitted, and what behaviors are required.

A vehicle's route from origin to destination crosses multiple jurisdictional authorities. The route manifest is composed by walking the marker sequence and accepting credentials from authorities the operating unit has admitted into its policy.

Route composition handles transitions between authority domains structurally. At a jurisdictional boundary, the unit re-evaluates which authority's credentials are present and adjusts mode accordingly. The transition is a structural event recorded in lineage.

Marker-track transport admits continuous operation across fully-marked, partially-marked, and unmarked stretches with mode transitions governed by composite admissibility. Progressive density solves the chicken-and-egg deployment problem that has stalled V2I for two decades.

When multiple vehicles platoon along a marker-track corridor, the marker sequence provides a shared coordination reference. Byzantine-robust consensus over the broadcasts allows platoons to operate even when a fraction of participating vehicles are misreading or adversarially misreporting.

Adversaries placing fake markers face the entire credentialing apparatus, not the per-vehicle sensor stack. A marker that doesn't match the credentialed sequence in expected position, or whose credential fails verification, is excluded from the route manifest.

State DOTs and federal regulators face the structural decision: continue certifying sensor stacks (impossible at scale) or shift to certifying segments and require operating units to prove they read certified segments correctly. The latter is within their existing expertise.

Marker-track agents admit a plurality of operator classes through a single architectural mechanism: passenger AVs, commercial freight, emergency response, transit, ride-share, personal mobility, and specialty industrial vehicles. The architecture parameterizes across classes through configuration rather than per-class re-implementation.

The dual-use marker article integrates retroreflective layer plus passive RFID plus governance-credentialed data plus optional PV/LED active illumination in one sealed enclosure. The article serves both human-driver visibility (the retroreflective lane marker) and autonomous-vehicle credentialing (the credentialed RFID payload).

Highway infrastructure deployed at scale provides credentialed marker positioning for autonomous vehicles. The dual-use marker article (retroreflective + RFID + credentialed payload) integrates with existing highway-marker manufacturing and installation processes.

Indoor positioning across hospitals, airports, retail, and large facilities benefits from credentialed marker infrastructure. The credentialed-marker primitive supports the indoor-positioning ecosystem without forcing platform-vendor lock-in.

Warehouse operations integrate credentialed RFID throughout pallet positions, racking, conveyance, and ground-truth ranging stations. The credentialed-marker primitive supports warehouse autonomy with audit-grade positioning lineage.

Agricultural operations across precision farming, livestock management, and emerging autonomous-equipment deployment face positioning and credentialing requirements that fit the dual-use marker primitive cleanly. Markers integrated into field infrastructure (gate posts, fence lines, equipment refueling points) serve both human-operator and autonomous-equipment requirements.

Construction sites integrate temporary safety markers, equipment-tracking infrastructure, and emerging autonomous-equipment deployment. The dual-use marker primitive supports construction-specific deployment with safety-driven and operational-driven dual purpose.

Mining operations face structural GNSS denial in underground environments and operational complexity in open-pit operations. Credentialed marker networks integrated into mine infrastructure support autonomous mining equipment, worker safety, and regulatory compliance.

National park, trail-system, and outdoor-recreation operations integrate trail markers, safety signage, emergency-response infrastructure, and emerging autonomous-recreation services (autonomous shuttles, e-mobility, search-and-rescue robotics). Credentialed markers support both human visibility and machine-readable positioning.

Stadium and large-venue operations integrate ticketing, security, concession-tracking, emergency-response, and emerging autonomous-service deployment. Credentialed marker networks across venue infrastructure support venue operations with audit-grade lineage.
